You need a large room to strip and reassemble an airplane—especially when it’s the biggest one in your fleet. In this panoramic photo you can see a half assembled Lockheed C-5M Super Galaxy during a major inspection at Dover Air Force Base in Delaware.

All C-5 aircraft in the U.S. Air Force inventory undergo an eight-year scheduled maintenance timeline, with one of four inspections occurring at regular two-year intervals. Such a major inspection–which includes disassembly and re-assembly–takes approximately 55 days, and more than 100 staff can be working on the aircraft at any given moment.
